Abstract
The invention discloses a three-phase asynchronous motor used for a vertical pipeline circulating pump. The three-phase asynchronous motor comprises a chassis and a stator, wherein the stator is positioned inside the chassis; a flange is arranged at the lower end of the chassis; an end cover is arranged at the upper end of the chassis; a drive-end bearing is arranged in the inner hole of the flange; a non-drive end bearing is arranged at the inner hole of the end cover; a bearing cover is arranged above the non-drive bearing; a rotating shaft is arranged through the non-drive end bearing and the drive-end bearing; a rotor matched with the stator is arranged on the rotating shaft; the drive-end bearing is a single-row angular contact ball bearing; the center hole of the flange is directly sleeved on the rotating shaft; and a preloaded spring is arranged between the non-drive end bearing and the bearing cover. The bearing system of the motor is easy to lubricate; the axial carrying capacity is higher; the operation is stable, light and quick; the noise is lower; and the average service life of the bearing of a motor system is prolonged.
Description
Technical field
The present invention relates to a kind of motor, particularly a kind of riser circulating pump threephase asynchronous.
Background technology
Existing riser circulating pump is that a vertical casing is arranged with the threephase asynchronous structure, be provided with stator in the casing inboard, lower end at casing is fixed with flange, the upper end of casing is fixed with end cap, the endoporus of flange has drive end bearing and below to be fixed with the drive end bearing lid, and there is non-driven-end bearing at the endoporus place of end cap, and the non-driven-end bearing top is provided with the non-driven-end bearing lid, by non-driven-end bearing and drive end bearing rotating shaft is installed, rotating shaft is provided with the rotor that matches with stator.Wherein drive end bearing is that two single-groove grooved place kick bearings are set up in parallel, adopt a deep groove ball bearing as floating end at anti-drive end, the motor of this structure, drive end two row bearing lubrication conditions are poor, occur often that single bearing lubrication was lost efficacy in advance and the phenomenon that causes the motor bearings system crash; The drive end bearing lid bears bigger axial force in the course of the work, and is fragile; Non-driven-end bearing lid is to the preload force deficiency of non-driven-end bearing, can't self-regulated, and noise is big during operation.
Summary of the invention
Stressed rationally, strong, the low noise riser circulating pump of the axial load bearing capacity threephase asynchronous of each parts overcomes the deficiencies in the prior art when the purpose of this invention is to provide a kind of simple in structure, motor operation.
Riser circulating pump threephase asynchronous of the present invention, comprise casing, be positioned at the stator of casing inboard, lower end at casing is provided with flange, the upper end of casing is provided with end cap, and the endoporus of flange has drive end bearing, and there is non-driven-end bearing at the endoporus place of end cap, nonpowered axle holds the top and is provided with bearing cap, by non-driven-end bearing and drive end bearing rotating shaft is installed, rotating shaft is provided with the rotor that matches with stator, and described drive end bearing is single-row angular contact ball bearing; The centre bore of flange directly is sleeved in the rotating shaft; Between non-driven-end bearing and bearing cap, be provided with preloaded spring.
Riser circulating pump threephase asynchronous of the present invention, because drive end bearing is angular contact ball bearing and single setting, make that the bearing of motor system is easily lubricated, axial carrying capacity is stronger, the brisk noise that operates steadily is lower, improve the average life span of electric motor system bearing, guaranteed the reliability service of motor whole system.The endoporus of flange directly is sleeved in the rotating shaft, make drive end bearing no longer utilize bearing cap to carry out axial restraint, ensured axial carrying and the positioning function of drive end bearing as the motor bearings system, avoided dependence to bearing cap, simplify the bearing arrangement structure, further improved axial bearing capacity.Between non-driven-end bearing and bearing cap, preloaded spring is arranged, keep the axial pre-load power of spring constantly, and can regulate voluntarily.
